To whom 'it mayA concern.-

Be it known that I, WILLIAM B. RICE, of Oakland,

durability, straight wooden axle-tree, and large wheels, I

which causeit to run steadier on uneven ground.

Axle-tree on the top of beams and platform, making the draught direct on the beams.

Leverage, which regulates the raising and lowering ofthe plows.

Screw-power, which regulates the depthlof plowing.

Temperho1es, which` regulate the taking or giving of land. l

To enable others skilled in the art to make and use my invention, 1 will pro eed to describe its construction and operation.

Figure l is a sectional side elevation of my machine, and

Figure 2 is a top view of the same.

A are temper-holes for giving or taking land.

B, uprights which hold the axle-tree and screw Vto place on land-side.

C, hinges on furrow-side to hold axle-tree and platform together. 4

D, plates on side of axle-tree, with slot cut in them to vprevent turning, so that the screw will stand perpendicular at any depth of plowing.

E, slot in axle-tree for screw to work in.

F, plate let into platform to hold bottom of screw. G, uprights for roller.

H, screw which regulates depth of plowing.

(t, roller for lraising plows out.

c, leverage .to hold -plow-beams down while plowing.`

el d, hinges for raising points of' plows out first. K

e, chain for raising the heel of plows up when out of ground.

f, wheel, so constructed as to put on the hind end of the'pole at-h, while plowing, to take the weight oil' the horses7 necks, and also to put ou the hind end of the beams at g, when going from place to place.

Before plowing, screw down the left plow to `whatever depth it is desired to plow. Lay ott' the land to be plowed. The next round, the right-hand wheel drops into lthe4 furrow, making the beams level when both plows cut. At any time, if it is desired to plowfdeeper, turn the screw H when, the next round, both plows will cut to depth regulated by the screw.

O'laim.

What I claim as my invention, and wish to secure by Letters Patent, is

The temper-l1oles A, in combination with the up- Y rights B, hinges O, 'plates D, slot E, plate F, uprigllts for rollers G,`sor`ew H, level' b, leverage c, hinges d d, chain e, wheel f, all substantiallyas set forth and described.
